WebJul 22, 2024 · The order would be undefined in that case. And molecularity is not even defined except for elementary reactions, so there is no question of molecularity for multi-step processes. – S R Maiti Jul 22, 2024 at 3:05 1 There is always one step that will be the slowest even if the difference is miniscule. By definition there can only be one slowest step. WebFeb 22, 2024 · The key difference between order of reaction and molecularity is that the order of reaction gives the relationship between the concentration of a chemical species and the reaction it undergoes whereas molecularity expresses how many reactant molecules are involved in the reaction.

WebMolecularity refers to the amount of distinct molecules involved in a reaction while order refers to the exponent to which the concentration terms are raised to obtain the rate of reaction. A unimolecular reaction isn't exactly a "reaction" if you look through common sense, as a single reactant cant actually "react" with anything. WebOrder and molecularity can be same only for elementary reaction and it is different for complex reaction. Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate-determining elementary step. Hence, Option "E" is the correct answer.
